Definitions

  • This invention relates generally to vehicles and refers more particularly to improvements in stabilizing equipment for vehicles.
  • the present invention concerns itself more spe- 5 cically with stabilizers of the bar type mounted on the vehicle in such a manner that when one side of the vehicle rises at a different rate than the other, the stabilizer reacts with a twisting action keeping the vehicle body on an even keel and thereby prevents body roll or side sway.
  • One of the principal objects of this invention consists in improving generally, stabilizers of the foregoing character by simplifying the construction thereof and by insulating the bar, as well as its connections, from metallic contact with either the sprung or unsprung assembly.
  • Another advantageous feature of the present invention consists in mounting the sway bar in rubber on either the sprung or unsprung assembly, in such a manner that the rubber mounting exerts a radial pressure upon the sway bar to dampen the action of the latter with a resistance increasing as the degree of rotation of the bar increases.
  • the mounting for the sway bar acts in a manner similar to a shock absorber to dampen the action of the usual suspension springs.
  • a further object of the present invention resides in the novel connection between the ends of the bar and the sprung or unsprung assembly of the vehicle, depending upon which of the latter assemblies the bar is mounted.
  • FIG. 1 is a fragmentary plan view of a vehicle equipped with a stabilizer constructed in accordance with this invention
  • Figure 2 is an enlarged plan view of a portion of the vehicle shown in Figure l;
  • FIG 3 is a fragmentary side elevational view of the construction shown in Figure 2, having certain parts broken away for the sake of clearness;
  • Figure 4 is a sectional view taken substantially on the plane indicated by the line li-li of Figure 3.
  • the sprung assembly Ill comprises a frame I2 having laterally spaced longitudinally extending side sills I3 secured in assembled relationy by suitable cross members, designated 'generally herein by the reference character I4.
  • the unsprung assembly II comprises an axle I5 extending transversely of the frame I2 beneath the latter and carrying road engaging wheels I6 at opposite ends thereof.
  • the sprung assembly I0 is supported from the unsprung assembly II by means of semi-elliptical leaf springs I'l extending longitudinally of the frame I2 at opposite sides thereof and having the free end portions suitably connected to the adjacent sill members I3 of the frame.
  • the central portions of the leaf springs are secured to the axle I5 by suitable U-bolts I8.
  • I provide means in the form of a stabilizer I9 comprising a spring steel bar 2U mounted upon ⁇ one of the aforesaid assemblies and means 2i connecting the opposite ends of the bar to the other of the assemblies.
  • a stabilizer I9 comprising a spring steel bar 2U mounted upon ⁇ one of the aforesaid assemblies and means 2i connecting the opposite ends of the bar to the other of the assemblies.
  • one of the principal features of the present invention consists in applying resistance to rotation of the bar 20 in such a manner that the degree of this resistance increases as the rotation of the bar increases.
  • 'Ihis feature is desirable in that it renders it possible for the stabilizer to perform thaddi tional function of dampening the action of the springs I1 through the bar 20 and is accomplished in the present instance by mounting the bar 20 in rubber in such a manner that the rubber exerts a radial pressure upon the bar sucient to resist rotation of the same.
  • a block of rubber 25 is secured to the underside of each of the sills I3 by means of a clamp 26 and the rubber blocks are formed with openings 21 therethrough for receiving the bar 20. Due to the U-shaped contour of the bar 20, assembly of the'latter on the frame may be expedited by forming the blocks 25 of two complementary sections.
  • the blocks 25 are held between clamps 26 under a slight compression and the openings 21 through the blocks are less in diameter than the diameter of the bar so that the latter will be frictionally engaged by the rubber.
  • the bar is in effect, gripped by the rubber blocks and since the blocks are held in the clamps under compression, it necessarily follows that the degree of resistance to rotation of the bar will vary in accordance with the elasticity of the rubber and the extent of compression of the latter by the clamps.
  • each 'of the clamps 26 is composed of two sections 28 and 29.
  • the two sections of the clamps cooperate to form a retainer for the rubber blocks 25 and the ends of these sections are extended laterally to provide attaching portions 30.
  • the attaching portions are apertured for receiving the studs 3
  • the rubber blocks not only dampen the action of the springs I1 by resisting rotation of the bar 20, but they also serve to insulate the bar from metallic contact with the frame I2 and in order that the bar will also be insulated from metallic contact with the axle assembly, the following construction is provided.
  • the links 23 are provided with tubular body sections 33 restricted adjacent opposite ends thereof to form shoulders 34 and having openings 35 in the side walls thereof beyond the shoulders for receiving the spaded end portions 36 of the extensions 22.
  • the openings 35 are elongated in the direction of the axis of the tubular sections 33 and have a width substantially less than the spaded ends 36 of the extensions.
  • the major axes 31 of the spaded portions 36 extend at substantially right angles to the major axes of the openings 35 in the assembled position of the bar 20 requiring the links to be rotated after the spaded portions are inserted through the openings so that the former extend transversely of the openings 35 when the links are in the position thereof shown in Figure 3.
  • the arrangement is such as to prevent accidental disengagement of the links from the extensions 22 of the bar 20.
  • the discs 31 Prior to inserting the spaded portions 36 into the upper ends of the tubular sections 33, the discs 31 are sleeved within the upper ends of the tubular sections for engagement with the shoulders 34 and the blocks 38 are telescoped within the latter ends of the tubular sections in seating engagement with the discs 31.
  • the spaded portions 36 are then inserted through the openings 35 in the upper ends of the links and after the imi; has been rotated .into the upper extremities of the links.
  • operating rubber blocks 33 are sleeved within the upper extremities of the links and are secured in place by means of closure members '40 threaded
  • the rubber blocks are fashioned to entirely surround the spaded portions 36 of the extensions 22 and are held under compression within the links by means of the closures 40.
  • the brackets 24 are also provided with spaded portions 4I similar to the spaded portions 36 and adapted to be extended through the elongated openings 35 in the lower ends of the tubular sections 33.
  • the brackets 24 are assembled with the lower ends of the links prior to securing the brackets to the unsprung assembly by the U-bolts I8 and the construction is such that when the brackets are in their operative positions shown in Figure 3, the major axes of the spaded portions 4I extend transversely of the openings 35.
  • the spaded portions 4I on the brackets 24 are imbedded in rubber blocks in the same manner as the spaded portions 36, with the exception that the rubber blocks in the lower ends of the links are secured under compression by means of a disc 42 held in place by crimping the lower extremities of the tubular sections 33 as at 43.
  • a stabilizer comprising a bar supported on one of the assemblies for rocking movement and having integral laterally projecting/f' extensions at opposite ends thereof, means mounting the bar in rubber on the last named assembly, means connecting the extremities of the extensions to the other of said assemblies including links having tubular portions at opposite ends thereof containing a yieldable material,
  • a sway bar and link assembly comprising, a torsion bar having integral laterally projecting extensions at opposite ends forming arms,
  • a sway bar and link assembly comprising, a torsion bar having integral arms extending laterally from opposite ends thereof and having elongated heads projecting from said arms at points spaced from the axis of the torsion bar,
  • links having hollow end portions and having elongated openings through the hollow end portions, the long axes of the openings being sufliciently greater than the long axes of the heads to permit inserting the heads through said openings into the hollow portions of the links and the small axes of the openings being less than the long axes of the heads to prevent displacement of said heads from the hollow portions of the links upon positioning the long axes of the heads transverse to the long axes of the openings, and resilient members secured under compression within the hollow portions of said links against opposite 'sides of said heads.
  • a sway bar and link assembly comprising, a torsion bar having integral laterally projecting extensions at opposite ends forming arms, the free ends of the arms being bent laterally and provided with elongated heads, links having hollow end portions and having elongated openings through the hollow end portions, the long axes of the openings being sufficiently greater than the long axes of the heads to permit inserting the heads through said openings into the hollow portions of the links and the small axes of the openings being less than the long axes of the heads to prevent displacement of said heads from the hollow portions of the links upon positioning the heads with the long axes thereof transverse to the long axes of the openings, and rubber inserts secured under compression within the hollow portions of the links on opposite sides of the heads to secure the links to said sway bar.
